扇区水泥胶结测井仪DTMN、DTMX分开原因分析

Analysis of Reasons for DTMN and DTMX Separation of Cement Cementing Logging Tool in Sector

文章主要从理论层面和故障案例方面分析了导致扇区水泥胶结测井仪衰减率偏小或回零从而导致DTMN、DTMX分开原因,并提供了详细的操作方法,帮助现场操作人员判断是极板故障还是贴靠因素而引起的固井质量资料异常问题原因,从而提高扇区水泥胶结测井仪在固井质量作业中的成功率。

This paper mainly analyzes the reasons for DTMN and DTMX separation caused by low or zero attenuation rate of cement bonding logging tool in sector from the theoretical level and fault cases,and provides detailed operation methods to help f ield operators determine the cause of abnormal cementing quality data caused by plate failure or adhesion factors.Thus,the success rate of cement bond logging tool in cementing quality operation in sector can be improved.
